Hi, I was just wondering if somebody could help me understand the differences between overclocking an older system (like a Socket A System) to a newer system like my E4500. With my old system I had a good understanding of the BIOS settings and knew what I was doing when I was overclocking. Now with my new system I have no idea of what any of the settings do. Jam, I know you have a good knowledge about newer systems, could you shed some light on this for me? Any sites that explain the differences between the older style systems to the new ones? I have a Gigabyte P35-DS3R motherboard. Here's a Pic of some of the BIOS settings I'm looking at: http://i145.photobucket.com/albums/... Thanks heaps for any help!

11 x 240 = 2640 To OC increase the multipliar(11) to 12 to make 12 x 240 = 2880 or any other combination of multiplier and 'CPU host frequency' to achieve the desired 'CPU frequency'. Set PCI-E freq. to 100Mhz just to make sure. If there's a way to set your 'Memory frequency' to 400, 533, or 667 do so. All the other settings are not used in overclocking with the exception of DRAM timings.

@ pgckkwvdzm, "To OC increase the multipliar(11) to 12 to make 12 x 240 = 2880" You can't raise the multiplier higher than the default...you can only lower it. Even so, raising the multiplier is not the best way to overclock because all it does is overclock the CPU. @ Mattwizz3, Just as with a socket A system, you should strive for a 1:1 CPU:DRAM freq ratio. You currently have the CPU freq at 240MHz, but the RAM freq is running at 400MHz (aka 800MHz DDR), so your ratio is 3:5. You have to change the "System Memory Multiplier" to 2.0, that way the RAM will always stay in sync with the CPU. If you were to lower the CPU multi to 8x & raise the CPU freq to 400MHz, the CPU would run at 3.2GHz & you'd be taking full advantage of your DDR2-800 RAM. Or if you don't wanna push your motherboard chipset that far, you could try the CPU at 9 x 333MHz (3.0GHz)...with these settings, the RAM would run as DDR2-667. By running the RAM at a slower speed than what it's rated for, you *should* be able to tighten up on the timings for even more of a performance boost. And as pgckkwvdzm said, you should always lock the PCI-Express at 100MHz. Just to add, if you have any Spread Spectrum settings, disable them.

Thanks jam. I went for the 3GHz option because I'm fairly happy with it anyways. At least now I have the ram running 1:1. Thanks for helping me out! Mattwizz3 Core 2 Duo E4500 2GB DDR2 800 Gigabyte P35-DS3R 512MB Asus 8600GT
